How a job runs

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Jobs near Hourston are often grouped with others in the same area, to make the most of each trip. Let us know if your dates have any give.

  1. First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

What we need from you

  • Point out any areas we must not close
  • Flag any permit to work we will need
  • Confirm the product named in the specification

Ask for a quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Fire stopping in Hourston, done properly

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. Site teams most often ask us about builders’ foam or ordinary silicone in compartment walls and head-of-wall gaps with no fire seal, on cable penetrations, small duct penetrations where the tested detail allows and pipe penetrations. Whether you call it commercial sealant work, mastic application or joint sealing, in Hourston it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Travel to smaller places like Hourston is planned so every penetration is sealed on one trip. Photos of the gaps, the services and the wall or floor type help us bring the right products.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Do you need fire stopping in Hourston?

Openings in fire-resisting walls usually appear when services are added or changed. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.

Most enquiries start with something like this:

  • Openings found when ceilings come down for a refit
  • Fire sealant pulled out of the opening
  • Openings left by services added after handover
  • Snag lists that include open service penetrations

For buildings in and around Hourston, fire-rated sealant is installed where it is specified, to the manufacturer’s tested detail.

Comparing quotes

  • Will failed sealant be removed rather than covered?
  • How long is the guarantee, and what does it include?
  • Whether their applicators hold CSCS cards
  • Is the sealant right for the movement and the substrate?

Choosing a commercial sealant contractor

What sealant work can’t fix

We check first that sealant really is the fix. It won’t put right:

  • Fire risk assessments, a job for a competent assessor
  • Approving the work on behalf of building control
  • Plastic pipes whose detail calls for a collar or wrap

If you’re not sure, just phone 01277 525 020 or use the quote form and we will give you a straight answer.

Where we work in Hourston

  • Small duct penetrations where the tested detail allows
  • Linear gaps at wall heads
  • Pipe penetrations
  • Joints between fire-resisting walls and floors
  • Cable penetrations
  • Service gaps in risers

Work for main contractors and building owners

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Hourston can sit alongside others in a wider programme.

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Why deal with it now?

Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed which is why earlier is better. Around smaller places like Hourston, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Early resealing prevents it.

Pricing service penetrations depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Why us?

  • Fully insured, including public liability cover
  • CSCS-carded applicators
  • Work to your specification and the manufacturer’s guidance
  • One phone line for London, the South East and Scotland

Compartment walls and floors in Hourston

Being on an island, Hourston means planning around ferry times as well as the weather. The specification and photos of each penetration let us bring the right products first time. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook expects service penetrations to keep at least the fire resistance duration of the wall or floor, with proprietary products, intumescent ones included, tested for their end use. We install what’s specified, to the product’s tested detail.

For a hotel such as Merkister Hotel (under half a mile south-west of Hourston), penetration seals are worth checking after any refit or services upgrade.

Hourston is about 11 miles north-west of Kirkwall, in the Orkney Islands. We cover Hourston and the rest of the Orkney Islands, with the same fixed quotes and 12-month guarantee as everywhere else. Our the Orkney Islands coverage takes in 51 places, large and small.

Surface by surface

Drylining partitions

Service holes through plasterboard are frequently oversized or ragged. An oversized hole may be outside the sealant’s range and we’ll tell you what the detail says instead.

Masonry and concrete

Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening.

Questions about Hourston

How do Scotland’s building standards affect fire-rated sealant in Hourston?

Under Scotland’s non-domestic Technical Handbook (clause 2.1.14), service penetrations should keep at least the wall or floor’s fire resistance duration, using products tested for their end use. We install what has been specified, to the manufacturer’s tested detail, while design and approval sit with the designer and the verifier.

Will you travel to Hourston on the island?

Yes. We work across every Scottish council area, and that includes island locations such as Hourston. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Does weather matter for sealant work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Can you work while the building is occupied?

Usually, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

When can you be on site?

Give us your site hours and any access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
